Clear View Screens on Large Ships: Centripetal Acceleration Explained
What is the purpose of the circular structures in the windshields of large ships?
Purpose of Clear View Screens
What is the centripetal acceleration of the rim of the screen?
Calculating Centripetal Acceleration
Centripetal acceleration (a) formula: a = ω²r
Where:
- ω = angular speed in radians/second
- r = radius in meters
Given that the screen has a diameter of 0.43m (radius = 0.43m/2 = 0.215m) and rotates at 1500rpm (157 rad/s), we can calculate the centripetal acceleration:
a = (157 rad/s)² x 0.215m = 5300 m/s²
Therefore, the centripetal acceleration at the rim of the screen is approximately 5300 m/s².
